Device for use with self-developing film

ABSTRACT

A device is provided for use in a camera utilizing selfdeveloping film. The film in question comprises a rupturable pod of processing liquid which is sandwiched between a pair of photographic sheets. Attached to the exterior of one of the sheets and disposed adjacent the leading end thereof is an elongated removable feeder tab. The device is disposed within the camera and includes a pair of elongated spreader members which are biased towards one another to assume a substantially superposed relation and define an elongated predetermined minimum gap through which the photographic sheets and the pod, when in a collapsed state, are caused to move. As the film moves through the gap, the pod is ruptured and the processing liquid uniformly spread between the sheets. Compression means are disposed adjacent the infeed side of the gap and provide uninterrupted pressure on the opposite marginal segments of the film sheets. Compressive pressure is continuously exerted on the opposite marginal segments of the film from a location substantially upstream of the spreader members into the gap between the spreader members and thereby confining the spread of the processing liquid to between the compressed marginal segments. Portions of the compression means extend into the gap and engage the film while the latter is moving therethrough. The device includes a guide means which is disposed adjacent the infeed side of the gap and directs the leading end of the film into the gap. The feeder tab carried by one of the photographic sheets is positioned over the guide member so as to circumvent the gap. The feeder tab projects outwardly from the camera housing and, as it is manually pulled therefrom, the feeder tab will cause the leading ends of the photographic sheets to pass through the gap and extend outwardly from the camera housing whereupon they may be grasped for manual pulling of the remainder of the film through the gap.

2 Sheets-Sheet 2 I 20? I20 BACKGROUND OF THEINVENTION Various deviceshave heretofore been provided for spreading the processing liquidbetween the photographic sheets of self-developing film upon the latterbeing moved a predetermined distance through a camera. Because ofcertain design characteristics,however, the devices have been beset withone or more of the following shortcomings: (a) they were of a complexand costly construction; (b) the spreader members were ineffective inuniformly spreading the processing liquid between thephotographic sheetsonce the pod containing the liquid was ruptured; (c) leakage of theprocessing liquid occurred along the margins of the film as the latterwas moved through the device; (d) the I film frequently became jammed inthe device; and (e) moving of the film through-the device was an awkwardmanual manipulation and often resulted in a failure to evenly developthe film.

SUMMARY OF THE INVENTION Thus, it is an object of this invention toprovide a device of the type described which avoids the shortcomingsaforenoted.

Y It is a further object of the invention to provide a device of thetype described which is of simple, compact and sturdy construction andmay be readily disposed within a camera utilizing self-developing filmwithout causing the size of the camera to be inordinately enlarged, orinterferingwith the normal operation of such a camera.

It is a further object of the invention toprovide a device of the typedescribed which requires little or no maintenance and is readily capableof handling either black and white or color self-developing filmpresently available on the market.

Further and additional objects will appear from the description,accompanying drawings, and appended claims.

In accordance with one embodiment of the invention, a device of the typedescribed, is provided which includes a frame, a pair of elongatedspreader members arranged in a substantially superposed relation anddefining an elongated predetermined minimum gap, and spring meanscarried by the frame and on which the ends of the spreader members aremounted. The spring means bias the spreader members toward one anotherto form the minimum gap. An elongated guide means is carried by theframe and is disposed adjacent the infeed side of the gap. The guidemeans is adapted to direct the leading end of the film into the gap andat the same time cause a feeder tab, which is normally a part of thefilm. to be diverted so that it will circumvent the gap. A compressionmeans is provided. which has first portions mounted on the frameadjacent the infeed side of the gap, and resilient second portionscarried adjacent the ends of the guide means and cooperating with thefirst portions to compress the opposite marginal segments of thephotographic sheets of the film, as the latter move through the gapbetween the spreader members. As the film sheets are moved through thegap, the pod of processing liquid, which is sandwiched between thesheets, is ruptured. The compressed marginal segments of the film sheetscause the spreading of the processing liquid to be confinedtherebetween. A part of each resilient second portion of the compressionmeans is disposed within the gap and is adapted to resiliently engagethe marginal segments of the film sheets as they move between thespreader members.

Referring now to the drawings and more particularly to FIGS. 1 and 2,one form of the improved device 10 is shown which is adapted to be usedin a camera, not shown, utilizing self-developing film 1 1 the latterbeing shown in phantom in FIG. 2. A camera of the type in question maybe that presently marketed by Polaroid cameras utilizing theself-developing film, whether the latter be black and white or color.The film 11, adapted for use with the device in question, consists ofsets of superposed sheets of film arranged in stacked relation within asuitable rectangular cartridge, not shown. The cartridge is sized sothat it may be readily slipped into a rear compartment of the camerawhen the latter is to be loaded or reloaded. The film cartridge may beof a type presently marketed by the Polaroid Corp. under the namePolaroid 3000 Speed, Type 107. Each set of film sheets used with thedevice 10 includes a rupturable pod of processing liquid which issandwiched between a pair of photographic sheets. Removably at tached tothe exposed surface of the uppermost film sheet, is an elongated feedertab T, which, when manually pulled, causes the leading edge E ofv thesuperposed film sheets to be properly positioned initially in the deviceso that said leading edge will be exposed outside the camera housing andadapted to be subsequently pulled manually in a manner to be hereinafterdescribed.

Device 10, as illustrated, includes a pair of elongated spreader members12 and 13 which take the form of rollers, disposed in superposedproximate relation. The term superposed, as used herein, is intended tocover the rollers being disposed in side-by-side or coextensiverelation. The rollers are biased towards one another by a pair ofsubstantially U-shaped springs 14 and 15. Each spring is of likeconstruction and is formed of a suitable resilient material for exertingthe necessary biasing force.

Roller 12 is provided at opposite ends thereof with annular shoulders12a which are adapted to tangentially engage the periphery of roller 13and form an elongated gap-G of predetermined minimum dimensions. Theouter surfaces of the rollers are smooth, so as not to mar or deface thefilm sheets as they move through the gap. Opposite ends of the rollersare provided with axially extending spindles 12b and 13a, see FIG. 6,which are adapted to be journaled in the corresponding ends of legs 14aand b and 15a and b of the springs 14 and 15.

Roller 12 is also provided with a pair of annular grooves or recesses12c which are disposed inwardly of, but adjacent to, the shoulders 12a.The function of the grooves will be discussed more fully hereinafter.

Positioned in close proximity to the infeed side of the gap G, is anelongated guide means which is shown as a roller 16. The roller 16 issupported at its opposite ends by upright side flanges 17a of a frame17, which will subsequently be described in greater detail. The guideroller 16 is substantially coextensive with the rollers 12 and 13 and isarranged in substantially parallel relation therewith. The centralportion 16a of roller 16 is recessed slightly. The opposite ends ofroller 16 are I each provided with a recessed bearing surface 16b and anaxially-extending spindle 16c, see FIG. 6. The spin dles 16c arejournaled in suitable openings formed in the frame side flanges 17a. Thedistal ends of the spindles 16c terminate within elongated slots 18formed in the corresponding upper legs 14a and 15a of the springs 14 and15..

The bearing surfaces 16b of guide roller 16 are embraced by coil springs20 and 21. The springs 20 and 21 are of like construction and each hasan end portion 20a or 2la which extends downwardly and forwardly fromthe bearing surface 1612, see FIGS. 3 and 9. The end portion normallyextends through the gap formed between the spreader rollers 12 and 13and terminates on the discharge side of the gap. The end portion 20a or21a is aligned with the annular groove 120 formed in roller 12. Thespring end portion 20a or 21a engages the marginal segments M of thefilm when the latter is moving through the gap, and is offset upwardly aslight 7 amount into the aligned annular groove 12c.

The opposite end portion 20b or 21b of spring 20 or 21, extendsrearwardly and downwardly from the bearing surface 16b and rests upon abase section 17b formfilm sheets is caused to pass prior ment enteringthe gap G.

As seen in FIG. 9, the surface 22a extends from a position substantiallybeneath the guide roller 16 to a position substantially at'the gap G.Thus, compressive force is exerted on the marginal segment M of the filmfor a substantial distance prior to the segment entering the gap G.Thus, by reason of this arrangement the possibility of the developingfluid leaking out from between the photographic sheets is eliminated. Invarious prior constructions, such leakage was a problem due to the factthat the compressive force exerted on the marginal segments was a pointcontact which occurred a substantial distance ahead of the spreadermembers and thus, there was a substantial distance wherein said marginalsegment was unsupported and not subjected to compressive forces. In theinstant construction, there is substantially uninterrupted compressiveforce exerted upon the marginal segment over a considerable distance oftravel of the segment prior to entering the gap G.

A depending flange 22b is formed adjacent the outer edge of surface 220.Flange 22b has a portionthereof which extends forwardly of the surface22a and has formed thereon, a laterally, outwardly extending bearto saidmarginal seging 22c. A center bore 22d is formed in the bearing and 1and 27 As seen in FIG. 6, the end of arm 14b is I notched at N toaccommodate the bearing 22c. The

collar 22c is spaced outwardly from flange 22b so as to accommodate notonly the notched end of arm 14b, but also a bifurcated portion 170 ofthe frame side flange 17a, see FIG. 6.

The rear, or upstream, portion of the support surface 220 bendsdownwardly, as seen in FIG. 7, to form a rear wall 22f. A depending lug22g is formed along the bottom edge of wall 22f and is adapted to bedisposed within a suitable opening 17d formed in the base section 17b ofthe frame 17. The'lug 22a serves to retain the component 22in a fixedposition relative to the carriage.

A studlike projection 22h is also formed on flange 22b and extendsoutwardly therefrom and is adapted to project through the bifurcated end170 of the frame side flange 17a and terminate within an elongated,vertically disposed slot 23' formed adjacent the end of spring arm 14aor 15a, see FIGS. 1 and 2. The elongated configuration 'of the slot 23permits relative movement of the spring arms and the spreader rollersing a part of the frame 17, see FIG. 9. Each forwardly 12 and 13 so asto enlarge the height of the gap G, when the film sheets move throughthe gap, without interference from the ends of the guide roller 16.

The upstream, or rearwardly extending ends of the spring arms 14a and b,or 15a and b, are interconnected by a loop portion or 150. Each loopportion is riveted at 24, or otherwise secured to the frame side flange17a. As a result of the springs 14 and 15 being secured to the frameflanges, the device 10 is of a unitary construction, thereby making itconvenient to handle when being assembled in a camera.

The frame base section 17b is of skeletal construction so as to reduceweight, and is provided with a rearwardly extending tongue 17d to whichis connected a leaf spring 25. The spring 25 is adapted to resilientlyengage the film cartridge when the latter is loaded into an interiorcompartment of a camera, and thus, retain the cartridge in properposition within said compartment.

The frame base section 17b is provided with a centrally disposed uprightprojection 172 which isadapted to engage the underside of the superposedfilm sheets 11, when the latter are being moved through the device. Theprojection 17e prevents any sagging of the film sheets as the sheetsmovetowards the gap between the spreader rollers.

A forwardly disposed projection 17f is also formed on the frame basesection 17b and serves to align the leading ends E (sometimes referredto as leader tabs) of the film sheets with the infeed side of the gap.The upper surface of the film sheets 11 will engage the underside of theguide roller 16 while the undersurface of the film sheets is engagingthe projection 17f.

As aforementioned, the central portion 16a of the guide roller 16 isrecessed, and said portion facilitates placement of the elongated feedertab T, removably attached to the top surface of the film sheets, overthe top of the guide roller 16 and the upper spreader roller 12. Thefeeder tab will extend through a suitable opening formed in the side ofthe-camera and be accessible for manual pulling. Upon the feeder tabbeing pulled out of the camera side, said feeder tab, in turn, willcause the film sheets to move and the leading ends E thereof to movethrough the gap and out of the camera housing through. a suitableopening formed in the latter. After one of the photographic sheets hasbeen exposed, the superposed film sheets are pulled completely out ofthe camera housing.

The size of the gap G formed between the spreader rollers, is such thatit is less than the thickness of the pod of processing liquid, which issandwiched between the photographic sheets and thus, said pod will beruptured when the film is manually pulled through the gap prior to beingremoved from the camera. Once the pod is ruptured, the spreader rollers12 and 13 will coact with the superposed sheets and cause the processingliquid to be uniformly spread between the sheets, The compressedmarginal segments of the sheets will confine, therebetween, spreading ofthe liquid.

Thus, it will be seen that an improved device, of the type described,has been provided which is compact, simple, and yet of sturdyconstruction. The device may be readily used with self-developing filmwhich is currently available on the market. The device will not mar ordeface the film as it is moved through the device and will effectivelyprevent the processing liquid from leaking out along the margins of thefilm.
